This paper investigates the effects of mandatory seat belt laws on driver behavior and traffic fatalities. Using a unique panel data set on seat belt usage rates in all U.S. jurisdictions, we analyze how such laws, by influencing seat belt use, affect traffic fatalities. Controlling for the endogeneity of seat belt usage, we find that it decreases overall traffic fatalities. The magnitude of th...

BACKGROUND Motor vehicle crashes were the leading cause of occupational fatalities in the United States in 2012, accounting for 25% of deaths. Truck drivers accounted for 46% of these deaths. This study estimates the prevalence of seat belt use and identifies factors associated with nonuse of seat belts among long-haul truck drivers (LHTDs), a group of workers at high risk for fatalities result...

Obese occupants have higher risks of fatalities and injuries in frontal crashes than normal‐weight individuals. In particular the chest and the lower extremities are the body regions that are more likely to be injured for obese than non‐obese occupants. Previous studies demonstrated that obesity increases the amount of belt webbing used by drivers, and have shown that lap belt placement tends t...

The purpose of this paper is to present the crash exposure patterns of pregnant occupants and to evaluate the effectiveness of restraint systems, including four-point seatbelts, in far side crashes. The NASS CDS database revealed that 53.0 % of pregnant occupants are exposed to frontal crashes while 13.5 % are exposed to far side impacts. Given that far side crashes were the second leading cras...

Seat belt legislation appears to have reduced mortality from, and the incidence of, serious head and facial injuries due to motor vehicle accidents. The use of seat belts has, however, also modified injury patterns in car occupants involved in accidents. This review traces the introduction of seat belt legislation and delineates the types of injury which have been attributed to seat belt wearing.
